"Anaerobic exercise in the form of high-intensity interval training was also found in one study to result in greater loss of subcutaneous fat, even though the subjects expended fewer than half as many calories during exercise.[2]"
Yes, but from the same source:
Whether this result was caused by the EPOC effect has not been established, and the caloric content of the participants' diet was not controlled during this particular study period.
I've found a couple of HIIT sessions a week has a more noticeable effect on my blubberiness than a regular diet of doughnuts audax rides.
Agreed. Audaxing isn't a great way to lose weight unless you very carefully control what you eat
HIIT certainly has its place - not least to stave off the boredom of LSD - but it will leave you glycogen-depleted. It may be that when you go out next day, you actually are using more fat because of that depletion.
I know that the exception to the audax non-weight-loss is an event like LEL or a 1000
if you push yourself - on the last day of the NF1000 in 2006 I couldn't get my heart rate into double figures, even in the hills, on fixed. I suspect that's because I was running on fat, having burned away a lot of fast-release glycogen.
I've also noticed that I drink next-to-nothing in that situation. PeterM commented on it on LEL - I filled my second bottle and he said "I bet you don't touch that all day". He was right.
